Timeline Activities¶

Yamcs UI¶

The Timeline chart in the Yamcs UI does not directly allow to submit activities. Instead you can do so from dedicated pages:

• To execute a command activity at a later time: go to Commanding ‣ Send a command, then select Send later....

• To execute a stack activity at a later time: go to Procedures ‣ Stacks, then on the page of a specific stack, select Schedule.

• To execute a script activity at a later time: go to Procedures ‣ Run a script, then select Run later....

In any of these cases, a dialog will open where you can specify the activity's details:

You need to provide at least a Label and the Execution time. The duration will automatically be set to 0 (unknown).

The Start automatically field indicates whether the activity will automatically start at the planned start time. If unchecked it will instead go into a READY mode, waiting for the user to indicate that the activity is actually underway.

Optionally you can associate tags with this activity. Tags are free-form text fields. This information is used by Item Band to select which activities are rendered: any activity that has at least one tag that matches one of the band's tags will be displayed on that specific band.

If you don't associate any tags, the activity will only be displayed on bands that do not have any tags defined.
